3/5n - 4/5 = 1/5n....multiply everything by 5 to get rid of the fractions
3n - 4 = n
-4 = n - 3n
-4 = -2n
-4/-2 = n
2 = n <==
Answer:
can i see a pic
Step-by-step explanation:
Answer:
d) 35ft
e) 6 seconds
f) 250°
Step-by-step explanation:
If it makes one rotation (360°) in 36 seconds, then it turns 10° every second.
36 secs = 360°
⇒ 1 sec = 360/36 = 10°
d) After 9 seconds, it has turned:
9 x 10 = 90°
Therefore, it will be 15 + 20 = 35ft from the wall
e) 60° = 6 seconds
f) 25 seconds = 25 x 10 = 250°
Minimum salary: $250
Sales: 1515
Commission: 5.65% x 1515 = $85.5975
Gross Salary: 250 + 85.5975 = $335.5975
For this, just plug in 1.5 into the x variable of this function and solve as such:
![f(1.5)=-16*1.5^2+112\\f(1.5)=-16*2.25+112\\f(1.5)=-36+112\\f(1.5)=76](https://tex.z-dn.net/?f=%20f%281.5%29%3D-16%2A1.5%5E2%2B112%5C%5Cf%281.5%29%3D-16%2A2.25%2B112%5C%5Cf%281.5%29%3D-36%2B112%5C%5Cf%281.5%29%3D76%20)
